To all whom 'it may comeam:

Be it known that I, JESSE citizen of the United States of America,residino' at Detroit, in the county of Wayne and tate o Michigan, haveinvented certain new and useful Improvements in Chain- Driven Trolleysfor Conveyers, of which .the following is a specification, referencebelng had therein to the accompanying. drawings.

The invention relates to conveyers an consists in 'the novelconstruction of chain driven trolley as hereinafter set forth.

In the drawings:

Figure l Dis a cross-section through a portion of an oven showing thearrangement of the trolley and portions of the conveyer inside andoutside of the oven;

Fig. 2 is a side elevation of the trolley.

It is the object of the invention to obtain a simple and compactconstruction of trolley A which is adapted for use where clearance spaceis small. Thus in the constructlon shown the ovenA, which is of tunnelform having an arched roof, is provided with tracks'B arranged in theupper portion of the tunnel as close to the roof as possible, so as togive the maximum s ace for the work. The conveyer Q is a link c ain andis-located just beneath'the roof and above the'trolleyaxle. 'The trolleyconsists of a-triangular member D' having separated side" platescross-connected at opposite endsby the bearings E for the chain ivots. Fare half-bearings on the depen mgcentralportion of the member D, saidbearings projecting out' ward from the side plates and being rovidedwith coperating bearing caps secured thereto by the bolts H. I is atrolley axle clamped in the bearings F, G and projecting beyond the sameto form journals for the trackwheels J. K is a work supportin hangerwhich at its upperend is forme into a hook L engaging the portion of theaxle which is between the bearings F.

With theconstruction as described the hangers K may be readily en agedwith the axles and disengaged there rom and will carry the load directlyinto the track wheels E. MCBRIDE, a.

and tracks B. At the same time the longi tudinal movement of theconveyer. is transmitted to the trolley throughthe medium of the linksand triangular member D. As the chain is arranged in the center of thearch, clearance space is available, which would not be in the plane ofthe trolley wheels. Also the arrangement of the chain above the trolleyaxles permits of engaging the hangerswith the axle without-interferencewith the chain. Y

The return portion of the conveyer may be arrangedo'utside of theItunnel, as shown in Fig. l, the chain occupying the space betweenthetracks and as the lhangers are detached before the return of theconveyer there will be nothing to interfere with this arrangement ofparts. p i

, What I claim as my invention is:

1. A conveyer trolley, comprising spaced triangular plates h`ving'connecting' ivot bearings at two of he angles thereo andoutwardly-extending bearings at the third angle, an axle clamped in saidthird bearing, trolley wheels journaled thereon, and a hanger hooked toengage said axle intermedlate said plates.

bearings, an axle clamped .in said central bearin and a hanger forengaging a por said axle intermediate said plates and clamping bearings.

In testimony whereof I aix my sglnature.
